1. Which of the following best describes an endothermic reaction?

• A. A reaction that absorbs heat
• B. A reaction that releases heat
• C. A reaction that does not involve heat
• D. A reaction that remains at a constant temperature

Correct answer: A

Rationale: An endothermic reaction is a process that absorbs heat from its surroundings. When a reaction absorbs heat, it leads to a decrease in the temperature of the surroundings, making choice A the correct description. In an endothermic reaction, energy is taken in from the surroundings, resulting in a decrease in temperature around the reaction site. Choice B is incorrect because a reaction that releases heat is known as an exothermic reaction. Choice C is incorrect as all reactions involve heat to some extent. Choice D is incorrect as an endothermic reaction does not remain at a constant temperature but rather absorbs heat, leading to a temperature decrease in the surroundings.

2. Which word is not spelled correctly in the context of the following sentence? The attending physician led a small entourage of students and interns.

• A. attending
• B. lead
• C. entourage
• D. interns

Correct answer: B

Rationale: The correct answer is B, 'lead.' The correct spelling should be 'led' in the context of the sentence. 'Lead' is a present tense verb, while 'led' is the past tense of 'lead' when used in the sense of guiding or showing the way. Choice A, 'attending,' is spelled correctly. Choice C, 'entourage,' is spelled correctly. Choice D, 'interns,' is spelled correctly. The error lies in the verb 'lead' being used incorrectly in the past tense form.

3. A family uses 12 gallons of water every day. How many gallons do they use in a non-leap year?

• A. 4,120 gallons
• B. 4,380 gallons
• C. 3,840 gallons
• D. 4,350 gallons

Correct answer: B

Rationale: To determine the total gallons the family uses in a non-leap year, you have to multiply the daily consumption by the number of days in a non-leap year. So, 12 gallons/day x 365 days = 4,380 gallons used per year. Therefore, the correct answer is B. Choice A is incorrect as it provides an inaccurate total by not considering the total days in a year. Choice C is incorrect as it offers a lower value due to not multiplying the daily usage by the total days in a year. Choice D is incorrect as it doesn't accurately calculate the total gallons used in a non-leap year.

4. Select the word or phrase that will make the sentence grammatically correct. The village is not very far _________ the railway station.

• A. to
• B. from
• C. by
• D. next

Correct answer: B

Rationale: The correct preposition to use in this sentence is 'from.' When referring to the distance between two locations, we use 'from' to indicate the starting point and 'to' to indicate the destination. In this case, the village is not very far from the railway station, showing the distance between the two places. Choice A ('to') is incorrect as it implies the village is far in the direction of the railway station. Choice C ('by') is incorrect as it suggests proximity rather than distance. Choice D ('next') is incorrect as it indicates the location of the village in relation to the railway station, not the distance between them.

5. In the following sentence, which word or phrase is the subject: 'The nurses went to the conference room.'

• A. conference
• B. went to
• C. room
• D. nurses

Correct answer: D

Rationale: In the sentence, 'The nurses went to the conference room,' 'nurses' is the subject. The subject of a sentence is typically the noun or pronoun that carries out the action or is described in the sentence. In this case, 'nurses' is the noun performing the action of going to the conference room. Choices A, B, and C are not the subject. 'Conference' and 'room' are objects of the prepositions 'to' and 'the,' while 'went to' is the verb phrase indicating the action performed by the subject.
